Hey all - I need to be using Fusion for several upcoming projects, and I've quickly gotten "GPU Memory Full" and crashes. I'm running a 3-year old PC - GTX 970 on an ASUS Z170 mobo with 32GB of DDR4/3200.

Will I be OK just upgrading the GPU? I'm thinking 2070. I'm not crazy about spending twice as much for a marginal increase in performance - but if it keep crashing when using Fusion, then it wasn't worth it ☺

Thanks, Glenn - I'm talking about using Fusion while within Resolve. I've never had issues with "GPU Memory Full" before, but now that I've got a very large image that I'm playing with in front of the camera/rendered within Fusion, it's complaining!

This may be a flaw of running fusion from within Resolve. With Resolve running as well it may be draining your system.

I only use stand alone fusion...but I've never had memory error issues. If I run it on my laptop...which is a z-book...but its 6 years old...the renders might be slower, but I don't think I've ever seen GPU full.

Your whole Resolve experience will improve with a better GPU. The 970 is ancient compared to your mobo. The critical aspect is the new GPU has enough onboard RAM as well. You might get better bang for buck on a GTX 1080ti. The newer RTX cards are better for ray tracing but I'm not sure Resolve leverages that performance. I've got a 4 year old mobo with a GTX 1080 and don't get GPU ram messages using any part of Resolve including the Fusion tab.
